Call for Papers

The 2nd International Workshop on Language Resources for

Content-based Image Retrieval (OntoImage 2008)

Held in conjunction with LREC 2008

Marrakech, Morocco

afternoon of May 26, 2008

*Scope *

* *

There are two computer-aided methods for accessing images:

* indexing textual descriptions (done mostly by public retrieval

engines)

o assigned manually on community sharing sites, e.g. Flickr;

o extracted from the text of the web page associated with the

image , e.g. Google

o extracting textual information inside the image using OCR

techniques

* indexing low-level visual features (colour, texture, etc.) of the

images (called Content Based Image Retrieval - CBIR).

Combining these two methods is currently a hot topic since it involves developing hybrid approaches using automatic image tagging from text along with low level visual features from an image to produce text metadata. One of the main limitations within state-of-the-art CBIR resides in the mismatch (the “Semantic Gap” in image analysis) between low-level visual descriptors and the human-understood semantics of picture similarity. There are problems of vocabulary at all levels in the description of an image. There is a mismatch between the text found around an image, between the keywords that people assign to an image, and between the objects that can be recognized in an image. How can available language resources (terminology, thesauri, ontologies, etc.) help? How much must they be altered to reduce the semantic gap?

This half-day workshop will present up to 9 papers examining the intersection of language resources and image analysis and retrieval.

We welcome submissions addressing the following questions:

* What elements in a lexicon correspond to picturable objects?

* How can language resources be used to organize and improve user

contributed image annotations?

* Which are the roles of language resources in image retrieval?

* How should language resources and image processing techniques be

integrated?

* How can current language resources be adapted for content-based

image retrieval in real-world applications, like the Web search?

* Can language resources and low-level visual descriptors be

organized into a joint knowledge infrastructure?

* Do we need new semantic structures (ontologies, thesauri) for

CBIR? Can we build them (semi)automatically?

* What visual characteristics of objects can be discovered by text

processing (color, size, location, shape, texture)?

* What is the relation between the lexicon and image indexing and

retrieval? What words should be associated with an image? Can this

be automated?

* How to combine speech and textual resources related to image data?

* What are some application areas where this research can be evaluated?

* *

*Submissions *

We expect extended abstracts describing research addressing one of the above questions of about 1500 words to be submitted as WORD, PDF or ASCII documents per email to the following address: adrian.popescu at cea.fr <mailto:adrian.popescu at cea.fr>

A reception notification will be sent to the authors within 48 hours. The final papers should have no more than 6 pages.
